Abstract

This community service activity aims to train the making of alternative energy kits to support the learning of the Merdeka curriculum, especially for grade X for physics teachers in Nganjuk district. Physics learning in the Merdeka Curriculum requires students to think critically and innovatively through a discovery process using a project-based learning model (PjBL). One of the applications of the PjBL learning model in physics is in the alternative energy material for grade X phase E. Based on observations, there is still a lack of supporting kits to support the chapter Alternative Energy. This Community Service activity is divided into several stages, namely: identification of problems and partner needs, Community Service preparation, Community Service implementation, training in making Alternative Energy kits, and evaluating the results of Community Service activities. All participants were very enthusiastic in participating in the activity. Even from the results of the response questionnaire using Google Form which was distributed to participants, it appears that the training material provided is relatively new, interesting, and inspiring. The results of the questionnaire also showed that the training material was relevant to the needs of teachers. Participants hope that similar activities can also be improved with technology-based learning media training.

Abstract

This study aims to evaluate the information technology security system at the Unit Sumber Daya Informasi (USDI) of Udayana University using the COBIT 5 framework, focusing on the APO (Align, Plan, and Organize) and DSS (Deliver, Service, and Support) domains. The use of information technology at Udayana University is crucial to support both academic and non-academic activities, making information management and security a priority. The COBIT 5 framework is used to assess IT management capabilities and identify gaps between the current and expected conditions. The research methods include questionnaires, interviews, and observations with unit leaders and staff at USDI. The evaluation results show that the APO 13 (Manage Security) and DSS 05 (Manage Security Service) subdomains have reached level 3 (established process), which means these processes have been well implemented. However, there is potential for improvement to level 4 (predictable process). This study provides recommendations to improve information security management, including establishing of an information security division, enhancing human resource competencies, preparing SOPs, and conducting regular internal monitoring and audits. With these improvements, it is expected that USDI Udayana University can optimally manage and protect the IT system, supporting institutional goals more safely and efficiently.

Abstract

Creative thinking skills are essential competencies in physics education because students are expected not only to understand scientific concepts but also to apply them creatively in solving contextual problems. However, learning in physics on Newton’s Laws is often still dominated by routine problem-solving and formula-based instruction, which provides limited opportunities for students to develop fluency, flexibility, originality, and elaboration. This study aimed to develop and evaluate STEAM-integrated Project-Based Learning (PjBL) learning tools on Newton’s Laws to improve students’ creative thinking skills. This research employed a Research and Development design using the 4-D model, consisting of Define, Design, Develop, and Disseminate stages, with dissemination limited to classroom implementation and academic reporting. The developed products included a teaching module, student worksheets, and a creative thinking skills test instrument. The study involved 55 eleventh-grade science students at SMA Labschool UNESA 1 Surabaya, selected through purposive sampling. Data were collected through expert validation, learning implementation observation, pre-test and post-test, and student response questionnaires. Data were analyzed using descriptive statistics, normalized gain, and a paired t-test. The results showed that the developed learning tools were very valid, with an average validation score of 88.30%. The effectiveness test indicated a substantial increase in students’ creative thinking skills, with the pre-test average increasing from 38.14 to 89.86 in the post-test, an n-gain score of 0.85 in the high category, a significant paired t-test result (Sig. < 0.05), and positive student responses of 85%. The novelty of this study lies in the explicit integration of PjBL syntax, STEAM components, and indicators of creative thinking into structured learning tools for Newton’s Laws. These findings indicate that the developed learning tools are valid, practical, and effective, and that they contribute to physics education by offering a contextual, interdisciplinary, and student-centered instructional design to foster creative thinking skills.

Abstract

Text preprocessing in Indonesian applications commonly relied on external libraries such as Sastrawi. However, performing this task outside the database layer often introduced significant latency due to data communication overhead between the application and the server. This study proposed and evaluated a native stemming mechanism utilizing the Nazief and Adriani algorithm implemented directly within an Oracle PL/SQL environment. The primary objective was to determine whether in-database processing could offer better performance than the standard application-layer approach. The assessment compared the PL/SQL implementation against the Python-based Sastrawi library using a comprehensive dataset of 54,715 words sourced from the Kamus Besar Bahasa Indonesia (KBBI). Performance metrics focused on stemming accuracy and total execution time. The empirical results revealed that the proposed PL/SQL method achieved an accuracy of 96.82%, which proved slightly superior to the 96.58% accuracy obtained by Sastrawi. Furthermore, the stored procedure implementation demonstrated significant efficiency, completing the process in 602.22 seconds, whereas the baseline method required 1,259.28 seconds. It was concluded that migrating the stemming logic into the database layer effectively reduced execution time by approximately 52.18% while maintaining high precision. These findings suggested that native database implementation provided a more robust solution for systems requiring high-performance text processing.

Abstract

Scientific writing is one of the essential skills that college students need to support research activities and the development of knowledge. However, students still encounter various challenges during the writing process. This study aimed to identify students’ responses toward scientific activities at FMIPA Universitas Negeri Surabaya and to examine the difficulties experienced by students in preparing scientific papers. The study employed a qualitative descriptive method using a purposive sampling technique. The research subjects consisted of 36 students from various study programs at FMIPA Universitas Negeri Surabaya who had been involved in research activities and scientific proposal writing. Data were collected through student response questionnaires consisting of closed-ended and open-ended questions. The data were analyzed descriptively and presented in tables and narrative descriptions. The results showed that most students had understood the existing student research programs and were familiar with the use of research guidelines. However, students still faced difficulties in systematically organizing research ideas, determining research variables and methods, finding relevant literature reviews, and connecting theories from various references. In addition, time management and the use of citation management applications were also obstacles for some students. Therefore, more structured assistance is needed through scientific writing training, reference searching training, and the use of citation management applications to improve the quality of students’ scientific writing.

Abstract

This study aims to analyze the profile of high school students’ critical thinking skills on temperature and heat topics through contextual tests integrating real-life phenomena into scientific reasoning. This research employed a quantitative descriptive approach involving 36 twelfth-grade students at SMA Negeri 9 Surabaya. Data were collected using critical thinking tests based on Ennis’s five indicators, supported by non-test questionnaires and teacher interviews. The findings revealed that students’ critical thinking skills were still categorized as low, with indicator achievement ranging from 46.4% to 59.0%. The inference indicator obtained the lowest score, while strategy and tactics showed the highest score. The novelty of this study lies in the in-depth analysis of each Ennis critical thinking indicator specifically applied to temperature and heat materials in real-world contexts. These findings highlight the need for developing contextual interactive learning media to stimulate higher-order thinking skills and improve students’ critical thinking abilities.

Abstract

Clock skew is the deviation of the clock from the true time, which makes it an important role in time information. Clock skew is unavoidable and causes each clock to run at a different speed, so there is a very slight difference between them, but it can still be observed properly. The known properties of clock skew make it potential research for many experts, such as Paxson, Aoki, and Huang. To produce a more accurate clock skew measurement, this study uses the ant colony optimization method by adopting the behavior of an ant colony in searching for food by choosing the path with the shortest route, which will become the cluster offset as a material for measuring clock skew. Ant colony optimization method has the most potential to be adapted in clock skew measurement because the cluster offset is not affected by the upper and the bottom outliers to produce an accurate clock skew measurement.
